AC4490-1x1
Overview
Laird tiny AC4490-1x1 radio modules put the power of wireless into the smallest, most cost-sensitive applications. Despite their small size, the modules can replace a mile of cable even in harsh industrial conditions. Using field-proven FHSS 900MHz technology that utilizes an unlicensed frequency band*, AC4490-1x1s reject interference, enable co-located system operation, and ensure data integrity. With the help of a unique transparent protocol (RF232), AC4490-1x1 integration is easy. OEMs simply solder the radio modules and antennas into place, then power-on. All frequency hopping, synchronization, and RF system data transmission/reception is performed by the radio module. The AC4490-1x1's standard TTL interface provides bi-directional communication in point-to-point and point-to-multipoint networks. A number of on-the-fly control commands accommodate varying wireless applications.

Can I get true full duplex operation from the RAMP products (RM024, AC4490, AC4790, LT1110, CL4490, CL4790)?
In the Laird RAMP line of products there is a feature called Full Duplex that leads one to believe they can talk upstream and downstream simultaneously. This is not the case, Full Duplex in the RAMP products gives a dedicated slot within the frame to the Server or Initiator and the second slot or next frame to the Client or Responder.
What is difference between AC4490/AC4790 product part numbers that end with -01, -02, -03?
The -01, -02, -03 at the end of the part number signifies the version of firmware loaded to the module.
These firmware versions are Regionally significant and apply certified for the regions listed:
